There are exactly hundreds of kinds of cold viruses there. You never know which one you will get, so there isn't a cure for each one. When a virus attacks your body, the body works hard to get rid of it. Blood rushes to your nose and brings congestion with it .You feel terrible because you can't breathe well, but your body is actually "eating" the virus. Your temperature rises and you get a fever, but the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells.  You may feel miserable, but actually your wonderful body is doing everything it can to kill the cold. Different people have different remedies for colds. In the United States and sane other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids.  Other people take medicine to stop the fever, congestion, and running nose. There is one interesting thing to note - some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight it and kill it .Bodies can do an amazing job on their own.  There is a joke, however, on taking medicine when you have a cold. It goes like this: The blood is    _   for the virus when someone gets a cold. A) peaceful B) safe C) useful D) deathful

A famous study was done in a school by a professor from a university. At the start of the school year, the teachers were given the names of five children. They were told that these five were the most excellent students in the class. But the fact was that these students were only average,and they were not the best students at all. Well, guess what? At the end of the year, all the five average students scored among the highest in the class. What made these average students change so much to become top students?The only difference was the change in their teachers' attitude. Because the teachers believed that these five kids were the top students,they expected more from them. And so these five average students began to believe and expect more from themselves. So they worked harder to do as well as they could. Do you know why? If you expect the best from people, they'll usually want to give you their best. A great leader said, "Treat a person just how he appears to be on the outside, and you'll make him even worse. But treat a person like he's already a success,and you'll help make him the best he can be." Like the true story of 7-year-old Johnny, his teacher got so angry with him that one day she said,"Johnny,you're the naughtiest boy in this class. I'm sure you'll never change." The next year Johnny had a new teacher. And on the first day of class,she met with Johnny after school and said,"Johnny, I've heard a lot about you! But do you know that I don't believe a word of it." And every day after that, this new teacher treated Johnny as if he was one of the smartest students even when Johnny did naughty things. Later on, Johnny became a school leader. Because that's the power of our belief and attitude toward children. What does the passage mainly tell us? A) Attitude and belief can change a person. B) Only teachers can make you a top student. C) A professor's study can help you score highest. D) If you want to get more,you should have new teachers.
